Theoden...good call...
The great thing about Psalms is grabs our hearts with Davids crys, pleas, petition and praise...when I insert myself into the Psalms in y prayer it so often describes exactly how I a feeling at that moment....David and I have become good friends since the beginning of this whole sit...thats all SorryDog

Psalm 51 has been a daily staple for myself..praying this on behalf of my wife...

A psalm of David. When the prophet Nathan came to him after David had committed adultery with Bathsheba
1-3Generous in love—God, give grace! Huge in mercy—wipe out my bad record.
Scrub away my guilt,
soak out my sins in your laundry.
I know how bad I've been;
my sins are staring me down.

4-6 You're the One I've violated, and you've seen
it all, seen the full extent of my evil.
You have all the facts before you;
whatever you decide about me is fair.
I've been out of step with you for a long time,
in the wrong since before I was born.
What you're after is truth from the inside out.
Enter me, then; conceive a new, true life.

7-15 Soak me in your laundry and I'll come out clean,
scrub me and I'll have a snow-white life.
Tune me in to foot-tapping songs,
set these once-broken bones to dancing.
Don't look too close for blemishes,
give me a clean bill of health.
God, make a fresh start in me,
shape a Genesis week from the chaos of my life.
Don't throw me out with the trash,
or fail to breathe holiness in me.
Bring me back from gray exile,
put a fresh wind in my sails!
Give me a job teaching rebels your ways
so the lost can find their way home.
Commute my death sentence, God, my salvation God,
and I'll sing anthems to your life-giving ways.
Unbutton my lips, dear God;
I'll let loose with your praise.

16-17 Going through the motions doesn't please you,
a flawless performance is nothing to you.
I learned God-worship
when my pride was shattered.
Heart-shattered lives ready for love
don't for a moment escape God's notice.

18-19 Make Zion the place you delight in,
repair Jerusalem's broken-down walls.
Then you'll get real worship from us,
acts of worship small and large,
Including all the bulls
they can heave onto your altar!
